Harbaugh also told reporters that Juan Castillo, the former offensive line coach and defensive coordinator of the Philadelphia Eagles, is on board to serve as the Ravens' run-game coordinator.

Caldwell -- who entered the season as quarterbacks coach -- has been in the interim coordinator role since December, and the Ravens have been a more aggressive offense under his watch.

Castillo is an intriguing pickup. The Baltimore Sun reported he has spent time with the Ravens in recent weeks and will travel with them to Super Bowl XLVII in his new role. Not a bad turn of events for the man who was scapegoated in Philly just months ago.
